FIGS. 1A-1C illustrate example views of rotation ofmount 100. The figures are merely illustrative of the shape of the mount and are not to scale.FIGS. 1A-C illustrate mount 100 comprising a firstadjustable device 110, a secondadjustable device 120 and a thirdadjustable device 130. A first intersection between the firstadjustable device 110 and the secondadjustable device 120 forms a firstprincipal axis 101. A second intersection between the secondadjustable device 120 and the thirdadjustable device 130 forms a secondprincipal axis 102. The secondprincipal axis 102 is substantially perpendicular to the firstprincipal axis 101. The firstadjustable device 110, secondadjustable device 120 and the third adjustable device are rigidly coupled together in substantially an L-shape. Although the intersections between the adjustable devices are illustrated as being straight lines, it is not necessary that the connections are straight. The connections may have any shape and still hold the adjustable devices substantially in an L-shape. - The
mount 100 is used to adjust a mounting plane, by adjusting each of the firstadjustable device 110, the secondadjustable device 120 and the thirdadjustable device 130. The mounting plane may be substantially parallel to the plane formed by thefirst axis 101 and the second axis. - The first
adjustable device 110 is configurable to be adjusted in a first translational degree of freedom providing a firstlinear adjustment 111 perpendicular to the plane of the drawing. The firstadjustable device 110 is also configured to substantially constrain the firstadjustable device 110 in remaining translational degrees of freedom in directions orthogonal to the firstlinear adjustment 111. The firstlinear adjustment 111 of the firstadjustable device 110 causes a rotation of the mounting plane about the secondprincipal axis 102 as illustrated inFIG. 1A . - The third
adjustable device 130 is configurable to be adjusted substantially in the first translational degree of freedom providing a thirdlinear adjustment 133 out of the plane of the drawing. The thirdadjustable device 130 is also configured to substantially constrain the thirdadjustable device 130 in remaining translational degrees of freedom in directions orthogonal to the third linear adjustment. The thirdlinear adjustment 133 of the thirdadjustable device 130 causes a rotation of the mounting plane about the firstprincipal axis 101 as illustrated inFIG. 1B . - The first translational degree of freedom of the first
adjustable device 110 is in the same direction as the first translational degree of freedom of the thirdadjustable device 130, i.e. in the direction of the third principal axis 103 (not shown inFIGS. 1A and 1B ). The second translational degree of freedom is perpendicular to the first translational degree of freedom and also in the plane formed by the firstprincipal axis 101 and the secondprincipal axis 102. - The second
adjustable device 120 is configured to be adjusted in a second translational degree of freedom providing a secondlinear adjustment 122. The secondadjustable device 120 is also configured to substantially constrain the secondadjustable device 120 in remaining translational degrees of freedom in directions orthogonal to the secondlinear adjustment 122. The secondlinear adjustment 122 of the secondadjustable device 120 causes a rotation of the mounting plane about the thirdprincipal axis 103 as illustrated inFIG. 1C . Thirdprincipal axis 103 is perpendicular to firstprincipal axis 101 and secondprincipal axis 102. - It is also possible that adjustment of the second
adjustable device 120 causes a rotation about the firstadjustable device 110 if the adjustment is parallel to secondprincipal axis 102 rather than being parallel to thefirst principle axis 101. - The adjustment of the first
adjustable device 110, secondadjustable device 120, and the thirdadjustable device 130 may be such that a dimension of the adjustable device changes. In some examples the adjustment may be enabled by a linear translational device. The linear adjustment device may comprise at least one of a screw jack, a pitched thread, an eccentric axle, a slider, a rack and pinion, and a servo/solenoid, however it is not limited to the aforementioned examples, and any suitable mechanism may be used to adjust the device in a single dimension. In some examples the adjustment device may be adjusted only in substantially a single dimension at a time. - The
mount 100 is illustrated as being L-shaped, however it is noted that the shape may be substantially L-shaped, such that the angle formed by thefirst axis 101 and thesecond axis 102 is not exactly 90°. Deviation from the angle being 90° leads to cross coupling between adjustments, but the amount of cross coupling, and therefore the deviation from 90°, may be acceptable depending on the application of the mount. -
FIG. 2 illustrates a perspective view of themount 100 according to some examples.FIG. 2 additionally shows a schematic view of each of the firstadjustable device 110, secondadjustable device 120 and thirdadjustable device 130. Each adjustable device comprises a first end and a second end. Each adjustable device also comprises a rotation device located in a path between the first end and the second end. The mounting plane may be formed by the first ends, or may be formed by the second ends. The set of the first ends or the set of the second ends are configured to be fixed. The first ends and the second ends are not required to be located at the ends of the adjustable devices. The rotation device of each of the firstadjustable device 110, secondadjustable device 120 and thirdadjustable device 130 allows the first end of each adjustable device to rotate in three dimensions about the second end (or vice versa, depending upon which end is fixed). -

Theadjustable device 200 is a generic example of the firstadjustable device 110, secondadjustable device 120 and thirdadjustable device 130. Each of the firstadjustable device 110, secondadjustable device 120 and thirdadjustable device 130 may comprise similar features to theadjustable device 200. Theadjustable device 200 comprises afirst end 210, arotation device 220, adjustment means 230 and asecond end 240. In some examples themount 100 may comprise threeadjustable devices 200. -
First end 210 may be configured to be fixed in location.Second end 240 may form the mounting plane that a device may be mounted onto. However, alternativelysecond end 240 may be configured to be fixed in location andfirst end 210 may form the mounting plane that a device may be mounted onto - Adjustment means 230 is configured to adjust the
adjustment device 200 in one translational degree of freedom and substantially constrain the adjustment device in the remaining two translational degrees of freedom. In some examples the adjustment means 230 may be configured to change the permitted degree of freedom such that the adjustment means 230 may adjust the adjustment device independently in more than one translational degree of freedom.

rotation device 220 allows thefirst end 210 to rotate in three rotational degrees of freedom with respect to thesecond end 240 and/or the adjustment means 230. The rotational freedom of the adjustment device ensures, when the using three adjustment devices each comprising a rotation device that the adjustments do not conflict with each other. Without the rotation device an adjustment to one of the adjustment devices would have an effect on the other two adjustment devices, and therefore further adjustments would be needed to adjust the mount. This adds time for aligning devices, and is therefore inefficient. - In some examples the
adjustment device 200 may also comprise locking means to lock the adjustment of the adjustment means 230 and/or the rotation of therotation device 220. The locking means may comprise at least one of a locking screw, locking pin and a locking nut. - In some examples the

FIG. 6 illustrates anadjustable mount 600 to adjust azimuth, roll and elevation of a device mounted to theadjustable mount 600. Themount 600 is similar to themount 100 described with reference toFIGS. 1A-C andFIG. 2 .Adjustable mount 600 comprises anazimuth adjustment device 400, anelevation adjustment device 500, and aroll adjustment device 610.Roll adjustment device 610 may be identical to or substantially similar toelevation adjustment device 500.Arrow 620 indicates the direction of the front of the device to be mounted to theadjustable mount 600. -
FIG. 7 illustrates anexample arrangement 700 according to some examples. Theexample arrangement 700 comprises anadjustable mount 600 comprising anazimuth adjustment device 400, anelevation device 500, and aroll adjustment device 610. The ends of theadjustable mount 600 are mounted to a mountingplate 710. Theoptical device 720 may be attached to the mounting plate. - The
arrangement 700 provides flexibility as once theoptical device 720 is aligned and each of theazimuth adjustment device 400, theelevation adjustment device 500, and theroll adjustment device 610 are locked, then anyoptical device 720 and/or mountingplate 710 may be removed and replaced without the need to repeat the alignment. - In some examples the
optical device 720 may be a heads up display, or any other sort of optical display. In some examples the mountingplate 710 may be integrated with theoptical device 720 or may be separate to theoptical device 720. - In some examples the
arrangement 700 may be located in a vehicle such as an aircraft. In some examples the firstprincipal axis 101 and secondprincipal axis 102 may be aligned or substantially aligned with principal axes of the vehicle. This reduces cross-coupling of adjustments made to thearrangement 700. - The
arrangement 700 is not limited to adjusting the alignment of anoptical device 720, and anoptical device 720 is merely an example of a device that may be aligned.
